Answer is C
Output is:- IncorrectSpecial-CharacterNumber
for the letter Z in type method it returns Incorrect because the argument passed is Captial 'Z' but accordind to the condition z should be small 'z'
for the SpecialCharacter \ it returns Special-character
for the number 6 it returns Number
and all the 3 will get concatenated by + operator as they are strings the output will be as above.

only catch here is in type('\'')
\' is an escape sequence so it will match with special character '
